If you are asking for a teacher of Wicca you may be disappointed. You see, it is against the law for anyone to interfere in the religious upbringing of a minor without the consent of their parents. So until you are of legal age you are unlikely to find any reputable teacher who is willing to take you as a student.
That being said, although I won't be your teacher, I am happy to answer specific questions and to point you at good resources to get started on your path. So feel free to ask me questions either here in the Forums or by sending me a message on this site.
In regards to the original post, there are lots of amazing books on Wicca on Amazon, or in some bookstores, you could discuss with your parents the idea of exploring another religion like Wicca and see if they would be willing to assist in purchasing a book on the subject.
Many people would love a teacher, but it isn't for everyone, particularly if you are underage, or very new. Having a teacher can be great, but if you don't have the chance to form your own opinions or ideas you may find that a teachers misconceptions or personal beliefs get mixed up in fact, your own practice would match theirs exactly, warts and all.
Instead learning from different sources, such as online and in books can give you a wider range of knowledge and allow you to formulate your own beliefs, rather than taking them directly from another person.
